On Monday we had not one, not two, but three industrial gas disasters: a natural gas pipeline in Texas exploded killing one worker, injuring several others and sending a geyser of flame visible for miles around. a fireball explosion burned seven workers drilling for natural gas in west virgina. Authorities shut down activities at a Pennsylvania gas drilling site after a plume of toxic wastewater shot 75 feet into the air from a ruptured gas well, raining chemicals down on the site for 16 straight hours.
